Write the procedure to prove that different gases have different diffusion rates?​

According to Graham's law of diffusion, the rate at which a gas diffuses is inversely proportional to the density of the gas. The movement of gas molecules from one place to the other along the concentration gradient is called diffusion. When they are allowed to escape through a tiny hole under pressure, this phenomenon is called effusion.
